Have you ever encountered a situation where an electrical device was damaged due to high temperature? Or a device could not operate normally due to low temperature? These problems can be solved by using an Auto reset thermostat.

An Auto reset thermostat is an intelligent thermostat that can automatically monitor the temperature of the device and control the operating status of the device according to the set temperature value. When the temperature of the device exceeds the set value, the Auto reset thermostat will automatically cut off the power supply to protect the device from damage. When the temperature of the device returns to the normal range, the Auto reset thermostat will automatically reset and restore the power supply to allow the device to start operating again.

Compared with traditional thermostats, the Auto reset thermostat has the following advantages:

1. Automatic reset function: When the temperature of the device returns to the normal range, the Auto reset thermostat will automatically reset and restore the power supply, eliminating the trouble of manual operation.

2. Precise control: The Auto reset thermostat can accurately control the operating status of the device according to the set temperature value, avoiding the problem of device damage or non-operation due to high or low temperature.

3. High efficiency and energy saving: Auto reset thermostat can control the operating status of the equipment according to the actual temperature of the equipment, avoiding unnecessary energy waste and saving energy costs.

Auto reset thermostat is widely used in various electrical equipment, such as electric kettles, electric blankets, ovens, water heaters, etc. Its appearance not only improves the safety and reliability of the equipment, but also brings users a more convenient and comfortable use experience.

Structurer and application:

KSD301 Bimetal Thermostat series products are thermostats that use bimetallic disc as temperature sensing elements. When the appliance is working normally, the bimetallic disc is in a free state and the contacts are in a closed/open state. When the temperature reaches the action temperature, the bimetallic disc is heated to generate internal stress and quickly moves, opening/closing the contacts, cutting off the circuit, thereby playing a role in temperature control. When the appliance cools to the reset temperature, the contacts automatically close/open and resume normal working state. It is widely used in household water dispensers and electric water bottles, disinfection cabinets, microwave ovens, electric coffee pots, rice cookers, air conditioners, laminating machines and other electric heating appliances.

Precautions for use

When auto reset thermostat is installed with contact temperature sensing, the metal cover should be close to the installation surface of the controlled device. 

To ensure the temperature sensing effect, thermal grease or other heat-conducting media with similar performance should be applied to the temperature sensing surface. The top of the cover should not be collapsed, loosened or deformed during installation to avoid affecting the performance. 

Liquids should not be allowed to penetrate into the thermostat, cracks should not appear on the outer shell, and the shape of the external terminals should not be changed at will. 

When the product is used in a circuit with a current of no more than 5A, a copper core wire with a cross-section of 0.5-1mm2 should be selected for connection; when used in a circuit with a current of no more than 10A, a copper core wire with a cross-section of 0.75-1.5mm2 should be selected for connection. 

The product should be stored in a ventilated, clean, dry, non-corrosive warehouse with a relative humidity of less than 90% and an ambient temperature below 40℃.
